You need an mcmod.info file, I had the same problem here until I added a mcmod.info file into the zip of the mod.

Make sure the

"modid": "NAME",

is right. If I'm not mistaken that is FML's mod list freaking out because it has no name.


Please send me all the typo's you found, I'm from Belgium and I'm a little dyslectic and suck @ typing.
